... In recent years, planetary science has been able to give a more accurate description of the Solar System by means of observations made by Earth-based telescopes but also thanks to space exploration of planets, asteroids and comets. We study, therefore, the nature of comets and asteroids through spectroscopic and images analysis obtained from ground-based telescopes and from space missions. ...

... We obtained three high-quality ultraviolet spectra of the hot R Coronae Borealis type star V348 Sgr using the Faint Object Spectrograph of the Hubble Space Telescope (HST). The first of these spectra was obtained when the star was in a shallow minimum ( Delta V less than 1 mag), whereas the other two were obtained during a deep minimum ( Delta V ~ 6 mag). ... The extinction curves obtained using the spectra at deep minimum are quite different from those obtained using spectra at shallow minima. ...
